Editor errors in 2.3.2 (1 post)

After upgrading to 2.3.2 it appears not to like the functions.php file. and the editor shows all the code if you try to edits post <p> ect.

If you rename the functions.php this errors disappears, however i have no idea what is causing the problem..

Warning: Cannot modify header information - headers already sent by (output started at /public_html/cheap-holidays/wp-content/themes/talian-10/functions.php:249) in /home2/cheaperh/public_html/cheap-holidays/wp-includes/pluggable.php on line 391

In the funtions file around line 249 if that is corect i have this <?php
}
if ( function_exists('register_sidebar_widget') )
register_sidebar_widget(__('Translator'), 'widget_mytheme_mytranslator');
